Lyme disease, an infection which can cause "debilitating" symptoms, is spread to humans by the bite of an infected tick. The charity Lime Disease UK says ticks can be prevalent in woodlands and countryside areas as well as urban parks and gardens.
How is Lyme disease passed from person to person?
Lyme disease is transmitted to humans by infected ticks, usually through the bites of ticks that are immature and are termed "nymphs." The ticks (nymph stage) are tiny (less than 2 mm diameter) and take about 36-48 hours of attachment to the human before the bacteria that cause Lyme disease are transmitted.
